Re: [chuck-users] Electronic ChucK
Mike, The computer interface I am planning is an analog one. It will receive stereo audio from the headphones jack and send stereo audio to the line-in Jack. This way we can generate whatever signals we want from ChucK and pipe them into EChucK on adc.left and adc.right. We can also receive two separate audio signals on dac.left and dac.right. I was sort of generalizing the stereo input and outputs into a pair of do-anything audio outs and do-anything audio ins. This opens up many possibilities for ChucK to control EChuck or provide signals for EChucK. Don't have a filtered noise module in your EChucK module collection? Just write a ChucK program and you've got it. Want an analog multiplier but don't have a multiplier module? send the two signals to line-in, have ChucK multiply them, and receive your result on headphones out. That's the idea. The computer interface module will be just a quad opamp circuit with perhaps variable gain/attenuation and diode clamping for the line-in signals to protect your computer. It should be quite low in cost, just $5 or so in parts + profit margin for the seller. Other computer interfaces such as USB, parallel port, etc. are planned but I'm doing the simplest, easiest modules first to get a working prototype built and tested/working. Cheers! Les (Inventor)
Maybe off topic, but I've always liked the idea of patching physical
acoustic objects into modular synthesisers. Like spring reverb, but with
arbitrary objects, like pianos... I never did get 'round to buying myself a
sound bug... to me personally, if I get audio out of the digital domain,
then it tends to be into the acoustic rather than analogue electric. Just a
thought, but do you see a place for acoustic transducers in your system?

This is a really interesting idea. I'm very much into the "exciter-resonator" way of looking at synthesis and so of course I like to use spring-reverbs but that could be extended a lot further. Using a channel of ADC and DAC acoustical objects (like tubes with a speaker and mic) could be inserted into ChucK as well... but I wonder if the spring-reverb models could be extended to substitute things like -say- a reed for a spring. This is exciting (pun intended, I suppose), I wonder how practical this could be. Thanks for sharing this idea! Cheers, Kas.

Sounds like an idea. I was thinking you were talking about the CONTROLLING interface.

Are all these modules going to strictly Analog? Is there going to be some spec for a digital control interface? This is the part that I was thinking you were talking about. Mike
